To all whom t may concern lle it known that l, MICHAEL F. BuoeAN, a citizen of the United States, residing at l'aawrence, in the county of Essex and State lilassachusetts, have invented certain new and useful improvements in Safety-Razors; and l do hereby declare the following to be a. clear, and exact description oi' the int ve. Jion, such as will enable others skilled in the art to which itappertains to make and use the saine.

TChe present invention relates to improveu ments in safety razors, and more particularly to razors ated manuallv.

The object of the present invention is to provide au improved form of safety razor which is extremely compact and which presents a maximum sective cutting edge with the blade clamped securely in operative position.

lllith this object in view the several features of the invention consistl in certain novel features of construction, combinations and arrangements of parts, the advantages of which will be obvious to those skilled in the art from the following description.

in the accompanying drawings illustrating the preferred i'orm of the invention; Figure l represents a front View oi' the razor with the handle attached ready for use; Fig.

ln the illustrated embodiment of the invention a razor blade l is clamped to a cylindrical holder 3 having an opening extending throughout its length. The blade is shaped to conform to the curvature of the holder and is provided with cutting edges which overlie and extend parallel to the opposite edges of the opening in the holder, as shown clearly in Figs. 3 and d. ln order 'to guard the cutting edges oi' 'the blade, the holder. is

provided upon each edge of the opening with a series of guardr lingers Il which are curved in conformity with the curvature of the holder and extend beyond the cutting edges of blade member l is formed oi a thin, resilient sheet of metal bent to the required shape and clamped to the holder by-a clamping member 6 which is connected tothe holder 3 at one end by the engagement of a slot 7 with an undercut lug 8, as shown clearly in Figs. 3, 7 and 8. The opposite end of the clamping member 6 is provided With an annular ring 9 which stud 10 extending from the holder 3 and threaded to receive a' handle portion l2 which serves to clampthe ring 9 to the .tace 13 of the holder, .as shown clearly in Fig. 6. In order to prevent the displacement of the blade member 1 relative to the holder, ,either longitudinally7 or angularly, the blade member is provided with a slot l5 `which embraces the lug 8 formed upon the holder, and a small recess 16 arranged to receive a pin 17 projecting from the inner surface of the clamping member to secure the blade .in

position at its opposite end. It Will be obvious. to those skilled in the art that if the blade is always clamped in the same position in the holder, substantially only one cutting edge will be employed and in. order toy prolong the life ol? 'the blade it is made reversible., as shown clearly in Fig. 9, by providing a rect-anguluar slot l5 and a recess 16 at each end of the the position of' the blade may be conveniently reversed When desired. it Willbe noted that this construction 4is extremely compact in form and provides a maximum clamping area for the blade,`insuring that the blade Will be held rigidly in position and eilectually'preventing any tendency olf the blade to spring away from the holder and inflict a out. With the present construct-ion .the rounded surface presented by 'the holder and clamping member enables the razor to be successfully manipulated in hollows and depressions in the face andcut the hair much closer to the skin than is possible with a razor having a flat blade or guard.' -Fur thermore, the thin metallic blade curved in .conformitv With the curvature of the clamp ing member and holder enahles the various parts to be formed upon an are of relatively the blade in the usual manner. The

blade in order thatloosely surrounds a .short radius and at the same time causes the surfaceot the hade to adhere closely to the surface of the holder, thus more effectively protecting the cutting edge. further advantage of the curved type oi blade resides in the fact that it can only he resl'nxrl'iened by the employment ot special apparatus and the user is compelled to either buy new blades when the old ones become dull, or resharpen them in the manner or with the apparatus designated by themanut'acturer.

ln order to hold the razor more when in operation the handle portion is made extensible by the provision of a tubular member 18 which is provided with a stud 20 threadedly received in the end.v ot' the handle member 12, as shown clearlyin Fig.

3. When not inuse the member 18 vis insertedl in the `holder 3 and the stud 2l) is threaded in the handle l2 Afrom the opposite direction, as shown clearly in ll`ig. (l. the member 18 being provided with a reduced tinted portion 21 whichis received within the holder 3.

1While it is preferred to employ thespeci'iic construction and arrangement oi" parts shown and described, it will 'be understood that this construction and arrangement is not essential except so far as specified in the claims, and may be changed or modified without departing from tbeln'oader teatures ot' the invention.
